Description

Micro-mixer

Technical field

Even the present invention relates to a kind of in the situation that mix high viscosity fluid each other, mix the fluid that low viscosity fluid and viscosity exceed 3000 times of left and right of this fluid, also can avoid the low viscosity fluid intermittent entry and the micro-mixer that mixes with the state of stablizing liquor charging.

Background technology

In the particulate manufacturing process that has utilized crystallization etc. to carry out, chemical reaction process, propose to have to mix the various static mixers that two or more at least fluids is purpose.Wherein, the micro-mixer of supplying with the fluid that mixes in the miniature stream is attracted attention by the people as a kind of efficient mixing arrangement.

Micro-mixer has following mechanism: it is that the miniature stream of 10 μ m to 1000 μ m left and right will two or more at least fluids be divided into small liquid and flows that this mechanism is used for utilizing flow path width, and after mix.Owing to being divided into small liquid stream and causing diffusion length to shorten by being supplied to fluid in micro-mixer, mixing velocity is accelerated, and therefore compares with static mixer in the past, can mix efficiently at short notice.

As the structure of micro-mixer, the known blender (Y shape micro-mixer) that the structure of the stream that for example has Y-shaped is arranged.The Y-shaped micro-mixer has following structure: the stream that flows for first fluid and the stream that flows for second fluid is acute angle, be that Y-shaped ground intersects on a plate, thereby form a converging roads.Each fluid that is supplied to this blender is sentenced the laminar condition interflow at the cross part of stream, and the phase counterdiffusion, and is then mixed.

At the fluid (anisotropic viscosity fluid) that makes low viscosity fluid and viscosity exceed 10 times of left and right of this fluid with identical flow in the situation that circulate in above-mentioned Y-shaped micro-mixer, want to make the crushing of two kinds of fluids identical.That is, accelerate the flow velocity of the lower fluid of viscosity, dwindle the use cross section ratio of miniature stream.The flow velocity of the fluid that the viscosity that slows down on the contrary is higher also increases the use cross section ratio of miniature stream, thereby makes the crushing of two kinds of fluids form identical.In the situation that differences in viscosity is large to a certain degree, the fluid that viscosity is lower flows in minimum cross section with flow velocity at a high speed, thereby becomes the reason that causes the unsettled liquid streams such as intermittent entry.Therefore, have that fluid can't stably circulate, the problem of fluid-mixing equably.

In addition, even in the situation that increase accordingly the flow path cross sectional area of the miniature stream of interflow section with the differences in viscosity of two kinds of fluids, also can increase the mutual diffusion time of liquid, and the Combination of fluid also can descend.Like this, in miniature stream during the phase counterdiffusion, mix low viscous fluid existing problems scarcely each other, but when mixing anisotropic viscosity fluid, high viscosity fluid, the possibility of the problem that multiple Combination descends is higher at liquid.

As other micro-mixers except above-mentioned Y-shaped micro-mixer, known have a cascade type micro-mixer that for example has following structure: this structure is by the plate and folded form (for example, with reference to the patent documentation 1) of the flaggy that is formed with the micro-channel that flows for reactant B of the micro-channel that will be formed with the reactant A that is provided as blending objects and flow.Each micro-channel that this cascade type micro-mixer has is the state configuration of acute angle when observing with the upper surface of slave plate, each fluid collaborates in the chamber, interflow of the outlet that is arranged at each micro-channel, and then mixed.

The micro-mixer that the described chamber, interflow that is provided with stacked structure and fluid is collaborated of patent documentation 1 forms (outlet mixed type micro-mixer) has following structure: form miniature stream on each plate of two plates that stacked on top of one another configures, formed each miniature stream is towards mixing chamber and intersection as shared outlet.In addition, the flow path width of the blender of patent documentation 1 and the degree of depth are below 250 μ m, and being easy to fluid take the instantaneous mixing of low viscosity as object, rather than with high viscosity fluid each other, blender that the anisotropic viscosity fluid-phase is corresponding.Therefore, be in the described blender of patent documentation 1 there be in the situation of high viscosity fluid, anisotropic viscosity fluid circulation, might produce crushing, obstruction etc., thereby make circulation become difficult, can't mix fully.

In addition, the right-hand member C4 of housing C has efferent 5A, and this efferent 5A is made of with the connector 5C that is linked to peristome 5B the peristome 5B of the right part that is formed at housing C.At peristome 5B and be fixed between the side 11c of the duplexer 110 in housing C and be provided with the space, this space is communicated with the outlet of the first small tubulose stream and the outlet of the second small tubulose stream, the mixing S3 of the section performance function of mixing with second fluid as first fluid.As the volume of S3, the intensity of the stable circulation of the pressure loss, high viscosity fluid and anisotropic viscosity fluid that the need consideration produces, mixing force, device.The volume of S3 can be with the viscosity of each fluid, change accordingly as degree of mixing of purpose etc.Particularly, for making the different two or more fluid of viscosity (anisotropic viscosity fluid) circulation, can reaching the viewpoint of stable circulation when mixing, as the preferred 100mm of the volume of S3 ³Above, be more preferably 250mm ³Above.

In addition, due in the situation that the differences in viscosity between first fluid and second fluid more greatly, for example more than 10 times, the way that increases the sectional area of the mixing S3 of section in order to carry out stable circulation can obtain the uniform mixture of first fluid and second fluid, is therefore preferred.In addition, in the situation that the differences in viscosity between first fluid and second fluid is large and the flow of the flow-rate ratio low viscosity fluid of high viscosity fluid is large, the preferred sectional area that further increases mixing section.

For the viewpoint that can obtain to have mixed well the mixture that first fluid and second fluid form, preferably the area of section that is communicated with of the above-mentioned mixing S3 of section and outlet outlet the first small tubulose stream and the second small tubulose stream is 50mm ²Above, 100mm more preferably ²Above.

In addition, the area of section that the outlet above-mentioned mixing S3 of section and outlet the first small tubulose stream and the second small tubulose stream is communicated with is the low viscosity fluid stably circulation incessantly that the micro-mixer of 5 times～50 times of summation of sectional area of the outlet of the sectional area of outlet of the first small tubulose stream and the second small tubulose stream can make the anisotropic viscosity fluid, and can reach good mixing, therefore be preferred, be more preferably the micro-mixer of 10 times～200 times, further the micro-mixer of preferred 20 times～300 times.

As mentioned above, micro-mixer of the present invention can be as one sees fit be used for mixing high viscosity fluid each other, differences in viscosity is apart from larger fluid.In micro-mixer of the present invention, the first fluid that circulates in the small tubulose stream that the first plate has, the second fluid that circulates in the small tubulose stream that the second plate has flow into to mixing section.The efferent 5A of fluid from Fig. 1 that flows into to mixing section discharges outside micro-mixer, but the speed (inflow velocity) the when rate of outflow of the fluid of this moment flows into to the section of mixing with second fluid than first fluid slowly.Therefore, the invention people consider just like lower device, the liquid stream of vortex-like, the convolution stream of this device by producing fluid in mixing section, thus can utilize this liquid stream to mix efficiently first fluid and second fluid.

For being easy to produce the viewpoint that above-mentioned liquid vortex-like, convolution stream flows, distance between the export department of the section of mixing that the export department of the export department of the preferred first small tubulose stream and the second small tubulose stream and mixture for first fluid and second fluid circulate is 2mm～100mm, is more preferably 10mm～200mm.In addition, in the present invention, the export department of mixing section refers to the peristome that the 5B by Fig. 1 of mixture represents.
